removing 40C oil pump
I have looked and searched for info and can not find any on removing my oil pump from my 40C engine. The problem is after I removed my engine and went to disassembly the engine, once I clean the gunk and grime off the engine, I notice I no longer had anything that resembled a set screw to remove the oil pump. at one time the set screw got strip off and somebody started drilling the set screw out, and is now below the surface of the block. I tried drilling it a little deeper, and tried a easy-out but it is not working. I am thinking I may have to drill until I relieve the pressure on the pump housing. It would help if I knew how deep the set screw hole is before it touches the pump housing, Any help would be greatly appreciated.

Hi,
If you do not have left-handed drill bits, get some. They work amazingly well for this.

removing 40C oil pump
Thanks for the replies, I will just keep chewing away until the metal changes , I am using left turning drill bits and square and spiral type easy outs, nothing has broke lose I was curios at what depth I would hit the pump. by using a micrometer depth gauge I could stop before I damage the pump,
Thanks
Thanks

If you are good with a welder, you can go down in the hole and weld a column of weld up to the surface, then weld a nut on it. I use High Alloy 500 or Supermissleweld. They have a really hard flux that won't blow through if you touch the threads or something higher up on the weld.

Removing 40C oil pump
Thanks everybody for the suggestions, I had already tried everything except the welding idea. Well I did get it with a little to much grinding, I did drill a little into the pump shaft housing, nothing I can not fix. I have got both stuck pistons out, now to start the block clean up and get it ready to go to the machine shop. I will order my manuals tonight, any suggestions on who has the best quality for my money
